If there's enough friction to prevent the cubes from sliding down before picking up more, that also implies theres enough friction to prevent the cubes from sliding out, despite the direction of the flaps being with direction of motion of the cubes when sliding out. This is because to prevent the cubes from sliding down, theres extra friction required since the weight of the cubes exerts more torque about the root of the flaps
this is late, but it uses 8 motor base with passive angle which moves while driving backwards, and while the robot moves forward, the rollers move as well (with elastic thing that runs those 90 degree gear pairs)
Cool idea, but what would keep the stack from getting pulled over when you back off? All the weight from that expanding thing would be pushing down on the stack
Nice! I think it will work! Also, thank you for the animation. Just downloaded Blender. Can you please post the Blender animation file? This will be very useful for our project. Good luck in the competition!
The front of the basket/cube holding device is open, so then lean back to store the cubes. I think this is a little unrealistic because VEX robots tend to jerk and this might a pretty bad problem for this open front design.
